===Running Animation===

One of the very first things you may notice is Sonic's swirling legs in his running animation.

The entire running animation is different in the prototype compared to the final, and most importantly uses more frames.

† This is actually from ''Sonic 1'' final, as Sonic's blue color is slightly lighter. ''Sonic 2'' final's running animation is similar. The point here is to note the difference in the way Sonic's legs are drawn between the prototypes and the final version.

===Jumping/Spinning Animation===

Tails' jumping/spinning set of sprites doesn't have the reflective white spot in the prototypes.

===Spindash Animation===

There is no dust when Sonic or Tails is charging up for a spindash. The prototype charge-up sound is the normal spinning sound, and there is no release sound effect. Also you cannot re-charge a spindash in the prototype -- tapping the button does nothing.

'''Nick Arcade Prototype'''
 
−
<br/>In the Nick Arcade prototype, spindash increases your speed much less than in the Simon Wai prototype or final version. You can also hold a spindash on a breakable platform and Sonic will float in the air, instead of falling as he does in the other versions.
 
−
 
 
−
 
 
−
===Ring-Losing Behaviour===
 
−
 
 
−
When Tails is hurt, he looses rings on Sonic's behalf and the ring counter is reset. Furthermore, if Sonic and Tails are hit at the exact same time, loads of rings flow out regardless of the original amount of rings (as long as you have at least one ring).

It's worth mentioning that while Tails is invulnerable to spikes in the Nick Arcade prototype, he is still capable of losing rings in both early prototypes (and '''is''' vulnerable to spikes in the Beta). He does not lose his rings in the final release.

===Behaviour when hitting a wall (Nick Arcade Prototype)===
 
−
 
 
−
[[Image:comp_htired.png|left]]These sprites featuring Sonic sitting and standing up were found in the Simon Wai prototype by Scott Prower. It was originally believed that's Sonic when he's tired, but thanks to the discovery of the Nick Arcade prototype, we now know they were meant to be used when Sonic collides into a wall, like the following animation shows:
 
−
 
 
−
[[Image:comp_s2protohit.gif]]
 
−
 
 
−
This effect increases if Sonic is under water due to lower gravity.
 
−
 
 
−
As this is just a beta-programmed feature, some bugs results from it. Let's see an example.
